Remarks on result:

other: relative density: 3.71

According to the reference, the density values can be assumed to refer to temperatures near room temperature. For this reason 20 °C was filled in as temperature.

The relative density was calculated from the value of the handbook. The value was divided by the relative density of water (1.000).

Conclusions:

According to the reference, cobalt sulphate has a relative density of 3.71.

Additional information

For the evaluation of this endpoint data from two handbooks were used. According to the REACH regulation (“ECHA, guidance on information requirements and chemical safety assessment – chapter R.7a”), it is allowed to use specific handbook data as a reliable data source. Useful reference books and data compilations containing peer reviewed physico-chemical data include the Merck Index and the CRC Handbook of Chemistry and Physics.
